To all whom it may concern:

Be it known that I, FERDINAND SoIIonLLnR, chemist, a citizen of Germany, residing at Opladen, near Cologne-on-the-Rhine. Germany, have invented certain new and useful Improvements in Processes for Treating Horsehair Fabrics (for which I have filed applications in Germany on August 29th, 1919, Patent No. 336,881, and on October 24th, 1919, Patent No. 336,882), of which the following is a specification.

This invention relates to improvements in horse-hair fa'brics. It is well-known that fabrics woven of horse-hair or of horse-hair mixed with other textile fibres, such as are employed as insertion between the cloth and the'lining of garments, show the drawback that the hair owing to its smoothness and stiffness does not maintain its proper position within the fabric and thus soon renders the fabric useless for the purpose intended.

Sizing such as is employed for finishing other textile fabrics can not be employed for hair cloth as it makes it too stiff and brittle and prevents the circulation of the air.

According to this invention the individual hairs are ermanently secured in their correct position within the fabric by rubbing the cloth or fabric with such resins which greatly increase the friction, as for instance the resin employed for rubbing the strings of string instruments (colophony). The effect of the resin may be increased by applying the resin to the fabric in the form of a solution whereby the hair crossings are firmly united so that a displacement of the hairs is efiectively prevented. The same effect ma be obtalne'dif the resin is rubbed on the fa ric and subsequently melted by the application of heat to the fabric for instance by treating it with a smoothing-iron or assin it between heated rollers.

he fa ric ma also be steamed with solvents for the resin, whereby an adhesion of the hair crossings may be attained subsequently.

In carrying out the treatment the horsehair cloth ma for instance, be rub'bed, or powdered wit finely pulverized colophony either by hand or by the aid of a suitable brushing machine and this colophony may be melted by treating the cloth with a hot smoothing iron. The colophony may naturally be substituted by fossilized resins or some of the modern artificial resins as far as they are capable of considerably increasing the friction. Or the treatment of the cloth may be carried through on a Foulard or slmllar machine in which an approximately 5% alcoholic solution of colophony is applied to the cloth which is then dried. The solvent may be recovered in the usual manner.

The fabric or'c'loth treated with resin may also be subsequently saturated with dissolvedadhesives like glue, gelatine, dextrin, albumin, vegetable juices, sulfite waste waters, either by themselves or mixed together and then be dried. If desired the adhesives may be rendered insoluble by treating them with formaldehyde, salts of chromium or alum, in the well-known manner.

These substances well-known as sizing for finishing textile fabrics are quite ineffective for hair cloth without the preliminary treatment with resin and do not remove the smoothness of the hair.

The treatment may be carried out by impregnating the fabric previously treated with resin with a watery solution of gelatine 1 :5, squeezing and drying. Or the fabric treated with resin is impregnated with sulfite lye to which glue has been added, squeezed, treated with a 10% alum solution and dried.

What I claim as my invention and desire to secure by United States Letters Patent is:

1. The process for treating horse-hair fabrics, which consists in applying resin to. the fabric.

2. The process for treating horse-hair fabric, which consists in applying powdered resin to the fabric.

3. The process for treating horse-hair fabrics, which consists in applying owdered resin to the fabric and subjecting t e fabric thus treated to heat.

- 4. The process for treating horse-hair fabrics, which consists in applying resin to with resin, then with a sulfite lye containing 10 the fabric, then treatingthe fabric with an 50% glue, squeezing, treating with a 10% adhesive and drying. solution of alum and dryin 5.
